WILLIAM SHORTLO, OF SPRINGFIELD, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 418,387, dated December31, 1889.

Application filed March 9, 1889. Serial No. 302,606. (No model.)

To all whom it may concern.-

Be it known that I, IVILLIAM SHORTLO, of Springfield, in the county ofSangamon and State of Illinois, have invented a new and ImprovedCorn-Planter, of which the following is a specification, reference beinghad to the annexed drawings, forming a part thereof, in which- Figure 1is a plan view of my improved corn-planter. Fig. 2 is a front elevationwith a portion of the tongue removed, and Fig. 3 is a longitudinalsection taken on line 00 0c in Fig. 1.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to construct a simple and effectivemachine for planting corn and for check-rowing.

The invention consists in the construction and arrangement of parts, aswill be hereinafter described and claimed.

The frame A, forming the body of the machine, is supported upon the axleI3, upon which are loosely placed drive-wheels O, the connection betweenthe drive-wheels and the axle being made through ratchet-wheels a,secured to the axle, and spring-actuated pawls I), carried by thedrive-wheels. The forward end of the frame A is supported by acasterwheel D, the shank c of which extends upward through a nut cl,journaled 011 the frame A.

Upon the forward end of the frame A is secured a plank E, which supportsthe hoppers F, the said hoppers being supported upon cleats 6. Betweenthe cleats are inserted slidevalves G, which are connected by rods fwith arms g, carried by the rock-shaft H, and to the said shaft Harealso attached arms 71, which are connected by rods 71 with thedroplevers j, pivoted in the drill-points I, and arranged to drop thecorn at the proper instant.

To the center of the rock-shaft H is attached an arm J ,to which ishinged an extension K, the said extension being provided with a toe 7a,which strikes the under surface of the arm J and renders the saidextension and arm J rigid when the extension is pressed downward, aswill presently be described, but allows the extension K to lift freelywithout moving the arm I In the center of the axle B is inserted across-arm L, which is capable of striking the extension K whenever thesaid axle is turned by the forward movement of the planter, thus causingthe shaft 11 to rock and operate the valves G and drop-levers j. Aspring M, secured to the plank E, bears upon a toe Z, projecting forwardfrom the shaft H, and returns the shaft H and parts connected therewithto the point of starting. r

The hoppers F are provided with auxiliary valves N, operated by levers0, which are employed in shutting off communication between the hoppersF and the valves G.

In the rear part of the frameAis journaled a shaft P, to which isattached an arm Q, upon the end of which is journaled a marking wheel R,the said marking-wheel B being placed the width of a row from theadjacent drill-point I. The arm Q, can be turned by means of the wheelon on the shaft P, so that it will project from one side or the other ofthe planter, as may be required.

To the rear of the frame A is attached the drivers seat S, withinconvenient reach of the wheel m. To opposite sides of the frame A arepivoted rods 92, which are bent outwardly and downwardly at rightangles, and provided at their extremities with wooden cones 0, which aresupported from the drills I a distance equal to the width of a row, thesaid cones 0 being arranged with reference to the said drills so as tomake an impression on the ground when the end of a row is reached, so asto indicate the starting-point for the next pair of rows. The rods a(one rod only being shown) are bent up at their rear ends to formhandles it, by which the operator can raise and lower the cones.

, If, when the machine is backed, the pawland-ratchet mechanism fails towork, the retrograde motion of the tappetarm L will simply lift theextension K without producing any effect on the dropping mechanism,

Having thus described my invention, I claim as new and desire to secureby Letters Pa tent- 1. In a corn-planter, the combination, with the axlehaving an arm L, of the rock-shaft H, in front thereof, provided witharm g, the transverse arm J, secured to said rock-shaft and having a toeZ projecting in front of it,

and a rearwardly-extending hinged extension K, provided with aprojection extending under its rear end, and the plate-spring M, hearingon said toe, the hoppers F, and valves therefor connected with the armsg,substantially as set forth.

2. In a corn-planter, the combination, with the axle B, provided withthe arm L, of the shaft H, provided with the arms g, the arm J, carriedby the shaft H and. provided with the extension K, the toe Z, the springM, adapted to engage the said toe, the hoppers F, the valves G,connected with the arms g, the valves N, and the levers O, substantiallyas specified.

3. The combination, in a corn-planter, with the frame and droppingmechanism, of a rod at, extending; along oneof the side bars of theframe in front and rear bearings thereon and bent outwardly anddownwardly at its front end and upwardly at its rear end, as at n, andthe marker 0 on the lower end of the downwardly-bent end, substantiallyas set forth.

4. In a corn-planter, the combination, with the vertical shaft P,mounted in front of the drivers seat, of the reversible arm Q, extendingoutward from the lower end of said shaft and provided at its outer endwith a marking-Wheel R, and the operating-wheel men the upper end of theshaft P within reach of the driver, substantially as set forth.

In WILLIAM Sl-IORTLO.
